"The present invention relates to a knitted y stocking for varicose veins of the type comprlsin an opening for the passage of the heel, ormed during the knittin and sur- 5 rounded with a zone of double t ickness of fabric. l y

The stockin according to the invention is characterize in that the portion of doublel thickness of the heel has in the free state the form of a quarter of a sphere or of an ellipsoid and in rectangular p anes.

The invention relates to the method of manufacture of the above stocking, characterized in that the double portion lforming the heel is obtained by sewing along substantially rectan ular aces of two bands which Vare separate y knitted bythe simultaneous working of the needle banks of the machine. The annexed drawings will enable the above explanations to be better understood: Fig. 1 shows on a small scale a stocking according to the invention, placed in position on the leg.A

Fig. 2 is" a side view onvan enlarged scale of the part of the stocking adjacent the heel and is shown foot u wards, as it would be on the knitting machme.

Fig. 4 is a view in. perspective 'of t estocking after the bands are sewed together.

' r Fig. 5 is a section taken on line V-l-V of 'he stocking is knitted on a rectilinear machine with two needle banks of any known type, adapted to form a tubular web to which a tapering shape is given by means of suitable reductions. It will be assumed, for the sake of clearness that the front needle bank knits the front face 1 of the stockin (Figs. 1 and 2), theback bankknitting t e-,back face 2. The knitting is eiected in the-direction of the arrow 3. The line A-f-B repre;` sents the boundary of the two faces 1 and 2, that is to say the line of stitches formed by the outermost needles of each bank.

1 ven the point Bis reached, the work 1s stopped. The stitches are removed from the needles ofthe front bank and are mounted articular is bounded by two on a comb. The line of stitches thus arrested by the comb is shown by the line B-C.

The work is then resumed with both needle banks, but with only half the number of the needles, all those situated on one side of the axis being rendered inoperative. At the first stroke of the carriage one connects the stitches of the two needle banks which will give the line B-D (Figs. 2 and 3.) A tubular band of knitting is thus lformed to which, by means of suitable reductions, the shape B D F E will be given as clearly shown by Fig. 3.

At E F the knitting is sto ped and the needles which carry it are ren ered inoperative and the needles previously rendered inoperative are again brought into action, so as to knit, on the other half of the backace, a second tubular' band D F E B', symmetrical' with D F E B (Fig. 3).

Then the Sides DG and DG', FE and rn' vare respectively sewn together. The stockextent a quarter of an ellipsoid with cap removed. The front face 1 1s still held on the comb 4. d l

4 The stitches of the front face 1 are then remounted on the front bank of needles and the meshes of the selve'dge B E E B on the back bank. The selvedgeBE E B being greater-than the edge B C B', in order to put an equal .number of stitches of the two needle-banks some of the extreme stitches of the selveldge B, E,- E, B must be placed on the front needle-bank; that is to say the stitches B, H (Fig. 2) and the stitches B", H placedon the'other side with respect to the plane of the figure).

In recommencing the work in the usual fashion the foot ofthe stocking is formed by suitable reductions. rEhe limit of the working zones of the banks of'needles is the line H, J. By the above `method a stocking of elastic material is very simply produced and which, contrary to known stockings, takes the form of the foot without considerable deformation being required.

In practice, to connect together 'the two thicknesses constituting the tubular bands B, E, F, G, D, or B', E', F', G", D common lines of stitches 5 are formed.

I claim:

1. A method of manufacturingja stocking of the kind described on a. rectilinear knitting machine having two banks of needles, comprising the following steps: first, to stop the work on the front face of the stocking when the heel portion is reached; second, to knit with both needle banks two double-thickness bands with reductions on their interior edges; third, to sew together the upper edges of said bands; fourth, to resume the work on the front face of the stocking and, at the same time, on the exterior vedges of said' bands. t. 2. A method as claimed in claim 1, wherein the double-thickness bands are knitted separately and in succession, their interior edges being sewn to ther for"a. limited length starting from t e beginni of said bands. In testimony thereof I my signature.
